apt 1.0

April 4, 2014

APT 1.0 was released on the 1. April 2014 [0]! The first APT version was announced on the 1. April exactly 16 years ago [1].

The big news for this version is that we included a new “apt” binary that combines the most commonly used commands from apt-get and apt-cache. The commands are the same as their apt-get/apt-cache counterparts but with slightly different configuration options.

Currently the apt binary supports the following commands:

  • list: which is similar to dpkg list and can be used with flags like
    --installed or --upgradable.
  • search: works just like apt-cache search but sorted alphabetically.
  • show: works like apt-cache show but hide some details that people are less likely to care about (like the hashes). The full record is still available via apt-cache show of course.
  • update: just like the regular apt-get update with color output enabled.
  • install,remove: adds progress output during the dpkg run.
  • upgrade: the same as apt-get dist-upgrade –with-new-pkgs.
  • full-upgrade: a more meaningful name for dist-upgrade.
  • edit-sources: edit sources.list using $EDITOR.

Here is what the new progress looks like in 1.0:
apt-progress

You can enable/disable the install progress via:

# echo 'Dpkg::Progress-Fancy "1";' > /etc/apt/apt.conf.d/99progressbar

If you have further suggestions or bugreport about APT, get in touch and most importantly, have fun!

apt 0.9.12

October 12, 2013

The recently released apt 0.9.12 contains a bunch of good stuff, bugfixes and cleanups. But there are two new feature I particularly like.

The first is the new parameter “–with-new-pkgs” for the upgrade
command:

# apt-get upgrade --with-new-pkgs

that will install new dependencies on the upgrade but never remove
packages. A typical use-case is a stable system that gets a kernel
with a new kernel ABI package.

The second is “–show-progress” for
install/remove/upgrade/dist-upgrade which will show inline progress
when dpkg is running to indicate the global progress.

# apt-get install --show-progress tea

For the install progress, there is also a new experimental option
“Dpkg::Progress-Fancy”. It will display a persistent progress status bar in the last terminal line. This works like this:

# apt-get -o Dpkg::Progress-Fancy=true install tea

apt-install-fancy-progress

This kind of information is obviously most useful on complex operations like big installs or (release) upgrades.

New apt hits oneiric

August 8, 2011

I just uploaded a new apt to oneiric. Its a ABI break so there will be short time that the archive is in a state of churn while the packages are rebuild against the new ABI. But the good news is that apt finally got dpointers so we will require less ABI breaks in the future. Plus we moved the library into a proper library package making the transitions much easier from now on.

Ratings&reviews in software-center

January 28, 2011

Ratings&reviews support for software-center has landed last night in natty. A important step for us, thanks for all who were involved and a special thanks to our friends from the ISD team who made the server part of this work ready to rock.

Search suggestions in software-center

January 3, 2011

While the software-center team is currently focusing on ratings&reviews there are still some nice features landing in trunk. One I particularly like is the new search suggestions feature. It will suggest spelling corrections for package names or generic search terms:

It also offers suggestions when a search inside a category has no results:
